Izinyathelo Zokuqaphela Ukunakekela I-High Pressure Common Rail Diesel Generator

Umkhiqizi wejeneretha kadizili we-Cummins ukufundisa ulwazi lokulungisa: izinyathelo zokuqapha ukugcinwa kwamandla kagesi aphezulu ohlobo lwe-generator kaloliwe ojwayelekile.

1. Ukusetshenziswa kwansuku zonke

Ijeneretha ye-diesel yesitimela enengcindezi ephezulu ivamise ukuhlonyiswa nge-preheater.Uma iqalwa ngaphansi kwezinga lokushisa eliphansi, iswishi yokushisisa ingavulwa kuqala.Uma ukukhanya kwenkomba ye-preheater kukhanya, kukhombisa ukuthi i-preheater iqala ukusebenza.Ngemuva kwesikhathi sokushisa, ijeneretha yedizili ingaqalwa ngemuva kokuthi inkomba yokushisa ivaliwe.Inkomba yokushisa kuqala nayo inomsebenzi we-alamu.Uma inkomba preheating kubaneka ngesikhathi ukusebenza evamile ujantshi diesel generator, kubonisa ukuthi generator diesel uhlelo lokulawula lwehlulekile futhi kufanele lulungiswe ngokushesha ngangokunokwenzeka.

Ungasebenzisi amanzi anengcindezi ephezulu ukuze ugeze isistimu yomjovo kaphethiloli wejeneretha ye-diesel ejwayelekile, ngoba ngemuva kokuthi amanzi engena eyunithi yokulawula ye-elekthronikhi, inzwa, i-actuator nesixhumi sayo, isixhumi sivame ukugqwala, okuholela "kuphutha elithambile" okungukuthi. okunzima ukukuthola ohlelweni lokulawula lwe-elekthronikhi.

Iyunithi yokulawula ye-elekthronikhi, inzwa kanye ne-actuator yejeneretha ye-dizili yesitimela esine-voltage ephezulu izwela kakhulu ku-voltage.Ngisho noma ibhethri lilahlekelwa amandla kancane, lizophazamisa ukusebenza okuvamile kwesistimu yokulawula ye-elekthronikhi.Ngakho-ke, kuyadingeka ukugcina amandla okugcina ebhethri anele.Uma ukulungiswa kwe-welding kwenziwa ku-high-voltage common rail diesel generator, ikhebula lebhethri kufanele lihlakazwe, isixhumi se-ECU kufanele sinqanyulwe, futhi kungcono ukususa iyunithi yokulawula ye-elekthronikhi enembile.Amayunithi okulawula ama-elekthronikhi, izinzwa, ama-relay, njll. izingxenye zamandla kagesi aphansi, futhi i-overvoltage ekhiqizwa ngesikhathi sokushisela kulula kakhulu ukushisa amadivaysi kagesi angenhla.

Ngaphezu kwalokho, ukuhlinzwa okulandelayo kungenziwa kuphela ngemva kokuba ijeneretha ye-diesel enengcindezi ephezulu ivalwe okungenani imizuzu emi-5, ukuze kuvinjwe ukulimala komuntu okubangelwa umjovo kaphethiloli ocindezelwa kakhulu.

2. Izinyathelo zokuhlanza

Ijeneretha ye-diesel enengcindezi ephezulu inezidingo eziqinile zemikhiqizo kawoyela, kanti okuqukethwe kwesibabule, i-phosphorus nokungcola kuphansi kakhulu.Kufanele kusetshenziswe uwoyela we-diesel okhanyayo wekhwalithi ephezulu kanye namafutha enjini.Uwoyela we-diesel wekhwalithi ephansi kulula ukubangela ukuvinjelwa kanye nokuguga okungavamile kwama-injection kaphethiloli.Ngakho-ke, kuyadingeka ukukhipha njalo amanzi kanye ne-sediment ku-separator yamanzi kawoyela, futhi uhlanze njalo noma ubeke isihlungi se-diesel nesihlungi samafutha.Ngenxa yokuthi izinga likadizili elisetshenziswa amasethi e-generator yasekhaya linzima ukuhlangabezana ngokugcwele nezidingo ze-high-pressure common rail generator diesel, kunconywa ukusebenzisa izithasiselo ezikhethekile zedizili ukwengeza ethangini likaphethiloli nokuhlanza ukunikezwa kukaphethiloli. uhlelo njalo.

Ngaphambi kokuhlakaza isistimu yomjovo kaphethiloli, noma lapho umlomo wezingxenye zesistimu yomjovo kaphethiloli (njengomjovo kaphethiloli, ipayipi lokulethwa kukawoyela, njll.) kutholakala ukuthi lingcoliswe uthuli, kunconywa ukusebenzisa izinto zokudonsa uthuli ukuze umunce uthuli oluzungezile. , futhi ungasebenzisi ukufutha kwegesi enomfutho ophezulu, ukugungiswa kwamanzi anomfutho ophezulu noma ukuhlanza nge-ultrasonic.

Igumbi lesethi yejeneretha yokulungisa kanye namathuluzi kufanele kugcinwe kuhlanzeke kakhulu ukugwema ukunqwabelana kothuli.Egunjini lokubeka ijeneretha yokulungisa, izinhlayiya namafayibha angcolisa uhlelo lomjovo kaphethiloli akuvunyelwe, futhi imishini yokushisela, imishini yokugaya nezinye izinto ezingase zingcolise uhlelo lomjovo kaphethiloli azivunyelwe.

Izingubo zabasebenzi bezilungisa kufanele zihlanzeke, futhi azivunyelwe ukuthwala uthuli nezinsimbi.Akuvunyelwe ukugqoka izingubo ezithambile ukuze ugweme ukungcolisa uhlelo lomjovo wamafutha.Geza izandla ngaphambi kokusebenza ukulungisa.Ukubhema nokudla akuvunyelwe ngokuphelele ngesikhathi sokusebenza.

3. Ukuqaqa, ukugcinwa kanye nokuthuthwa kwezingxenye.

Ngemva komzila wesitimela ovamile wokucindezela okukhulu isethi ekhiqiza udizili egijima, kwenqatshelwe ukuqaqa uhlelo lomjovo wesitimela esinengcindezi ephezulu.Lapho ukhipha noma ufaka ipayipi elibuyisela uwoyela lephampu kawoyela enengcindezi ephezulu, phoqa eduze kwe-axial ukuze ugweme ukugoba.I-nati ngayinye izoqiniswa ku-torque eshiwo futhi akumele yonakaliswe.Ngemuva kokuba uhlelo lokuhlinzeka ngamafutha luhlakazwe, ngisho noma isikhathi sifushane kakhulu, i-cap yokuvikela ehlanzekile kufanele igqoke ngokushesha, futhi i-cap yokuzivikela ingasuswa ngaphambi kokuhlanganiswa kabusha.Izesekeli zesistimu yomjovo wesitimela esinengcindezi ephezulu kufanele zikhishwe ngaphambi kokusetshenziswa, futhi isivalo sokuzivikela kufanele sikhishwe ngaphambi kokuhlanganiswa.

Lapho ugcina futhi uthutha izingxenye zejeneretha zikadizili ezinengcindezi ephezulu, umjovo kaphethiloli, umhlangano wepompo kawoyela ocindezelwa kakhulu, umhlangano kaloliwe kagesi kanye nezinye izingxenye zesistimu yomjovo kufanele zigqoke amakepisi okuzivikela, futhi umjovo kaphethiloli uzosongwa ngephepha lamafutha.Izingxenye zizovinjelwa ekushayiseni ngesikhathi sokuthutha.Lapho uwathatha futhi uwabeka, angathinta kuphela umzimba wezingxenye.Akuvunyelwe ukuthinta amalunga amapayipi kawoyela ongenisayo naphumayo kanye nezimbobo zomlomo wesitokisi sikaphethiloli, ukuze ugweme ukungcolisa uhlelo lomjovo wesitimela olunomfutho ophezulu ovamile.
